Jim Dunlop: MXR M133 Micro Amp Pedal

With the simple yet ridiculously effective MXR M133 Micro Amp, you can add as much gain as you'll need with just a single control knob.

The Micro Amp is a fantastically efficient way to add a little something extra to your signal if, for example, you need a boost for a Guitar solo, or you are switching between humbuckers and single coils. You can also use it for a permanent boost to your volume or gain if you have a long effects chain and your signal is struggling to get through.
